There are a number of places in the PNW that grow wasabi, at least one on Vancouver island, one in Oregon, and I think one in Washington. The price at my local asian grocery store seems to range from $99 to $199 per pound over the last 3-4 years. Totally nonscientific, I just pay attention when picking up other herbs. I'd guess about $129/lb is normal there. I still haven't convinced myself to make a meal to justify the expense, I don't cook enough Japanese food.
